Phaseless Parametric Inversion for System Calibration and Obtaining Prior Information
IEEE Access, 2019 Electromagnetic inversion systems require that the experimental data be calibrated to the computational inversion model being used. In addition, accurate prior information provided to the inversion algorithm leads to higher-quality images.

Inverse problems for Lorentzian manifolds and non-linear hyperbolic equations [PDF]
, 2018 We study two inverse problems on a globally hyperbolic Lorentzian manifold (M, g). The problems are: / 1. Passive observations in spacetime: consider observations in an open set V⊂M .

Topological optimization and inverse problems
Computer Assisted Methods in Engineering and Science, 2023 The topological derivative of an arbitrary shape functional is introduced in [29] for 2D elasticity. The optimality conditions for general shape optimization problems are established in [30] using the shape variations including boundary and topology ...

A rainbow inverse problem [PDF]
ESAIM: Proceedings, 2010 Summary: We consider the radiative transfer equation (RTE) with reflection in a three-dimensional domain, infinite in two dimensions, and prove an existence result. Then, we study the inverse problem of retrieving the optical parameters from boundary measurements, with help of existing results by Choulli and Stefanov.

INVERSE PROBLEM FOR EINSTEIN-SCALAR FIELD EQUATIONS
, 2022 The paper introduces a method to solve inverse problems for hyperbolic systems where the leading-order terms are nonlinear. We apply the method to the coupled Einstein-scalar field equations and study the question of whether the structure of space-time ...
